NSYSU Develops Bio-plastic from Microalgae and Banana Waste, Wins International Innovation Gold Award

A team led by Professor Chang Keng-Ling from National Sun Yat-sen University's (NSYSU) Institute of Environmental Engineering has successfully developed an eco-friendly, carbon-reducing bio-plastic using marine microalgae and agricultural waste. This innovation won a Gold Medal at the 15th IIIC International Innovation and Invention Competition. The team developed an efficient ultrasonic extraction technique to use microalgae protein as a base and discovered that adding banana pseudo-stem powder as a filler significantly enhances the bio-plastic film's mechanical properties. This technology not only valorizes agricultural waste and promotes the circular economy but is also seen as a high-potential alternative to traditional plastics due to the rapid growth and low cost of its raw materials. Professor Chang also received the International Distinguished Inventor Award for his long-term contributions to environmental protection and plastic reduction.
